Why we do it

  • Coal (average) - 2.1 lb/kWh
  • Natural gas (average) - 1.0 lb/kWh
  • Renewables - 0.0 lb/kWh

The carbon footprint of electricity depends on the power source that generates it. And that source is constantly changing. Just 5 minutes can mean the difference between clean and dirty fuels.
